Converting To Mpeg Video

I have been given a list of specs by a client that I haven't been able to quite get specific enough in exporting from FCP 7 to Compressor 3.5.3. I've tried sending to Compressor from the Final Cut sequence and I've tried exporting a QT movie and importing it into Compressor. In a nutshell it needs to be a MPEG 2 Transport Streem, MPEG 2 Long GOP. Constant Bit Rate. I think I've figured out most everything except how to set the Video ID (481) and Audio ID (482). And how to set the Format Profile: Main@Main. Is there a way to find these in Compressor/FCP or is there a 3rd party software that would be better for encoding to mpeg? I've tried Mpeg Streamclip, MacX Video Converter and iMedia Coverter Deluxe and can't find all the settings I need in those either.
